If a circle has a circumference of 10 pie what is the circle's diameter?

Answer 1

Caroline Aucoin

#10# units.

#"circumference" = 2πr#

#10π=2πr#

#5π=πr#

#5=r#

The diameter is half of the radius, so

#5xx2=10# units.

Diameter #= 10#

#"circumference" = π * "diameter"#

Assuming that by "pie" you mean #π# (pi) ... your problem would be

#10 * π = π * d#

So you solve for #d#

#(10 * π)/π = (π * d)/π#

#d = 10#

The diameter of a circle can be found using the formula:

Diameter = Circumference / π

Given that the circumference of the circle is 10π, we can substitute this value into the formula to find the diameter:

Diameter = (10π) / π

Diameter = 10

Therefore, the diameter of the circle is 10 units.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
